Others may find this useful:
I have modified an existing library to work with YiFi101.
It is called WiFi101Twitter. and is attached.

There are two included examples with YiFi101tweet2.ino being the most developed

The code to send a tweet is not difficult- I have included a local function option in the second library example.

Time is obtained using the new WiFi101 function WiFi.getTime(). (which is a bit buggy at present).
TimerOne.h can be dowloaded from:
https://github.com/PaulStoffregen/TimerOne

You will need:
1) A twitter account

2) A token to post from http://arduino-tweet.appspot.com/oauth/twitter/login

3) The TimerOne and WiFi101Twitter libraries

I only use the Mega2560, so do post on use with other Arduino versions.

The code for YiFi101tweet2.ino is too big to post inline, however here is the header for details of the setup:

    */

// Support for tweet without library using function mytwitter
 
// time/date support using WiFi101 function WiFi.getTime()
//    date/time stamp added to tweet if time is available
// time maintained using system library <time.h>
// time incremented using 1ms interrupt generated by library TimerOne.h
// serial input parsed for new tweets
//    Serial '|' signifies newline and '>' signals send tweet
//           '|' = vertical bar, (shifted \), not 1, L or I
//    Signature defined by String Sig
